Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1-2, it is an embodiment of a kind of diffusion furnace mechanical manipulator axis servomotor of the utility model, comprising:
Admittedly connect and be the spindle nose 1 of right cylinder, axle body 2 and axle tail 3 successively. Flat dey joint (only a key mapping), discontinuity, on axle, the stress of splined end is concentrated bigger, therefore shaft head fairly weares and teares to make to connect and lost efficacy, the equipment accident that the disconnected boat of oar can be occurred time serious broken, therefore splined mode is adopted, spline keyway 4 it is provided with uniformly in spindle nose 1 left part, the degree of depth is 0.6cm-1cm, because its degree of depth is much less than flat key keyway, tooth root place stress is concentrated also less, and the strength reduction of uniform force, axle and hub reduces the work-ing life that can extend axis servomotor; Which reduce the number of times changing axis servomotor, decrease the fault-time thus brought, reduce the labour intensity of employee; Ensure that the Homes Using TV of equipment, reduce the cost in workshop. Spline keyway 4 has four, and on spindle nose 1, distribution is rationally, and convenient processing, under the prerequisite of proof strength, reduces the material loss processed and bring, reduces tooling cost further.
It is provided with axle journal 5 between spindle nose 1 and axle body 2, between axle body 2 and axle tail 3, it is provided with the axle collar 6. Axle journal 5 is the parts of a connection location, for installing bearing, comprise the first end difference 51 and second-order ladder portion 52 that are right cylinder, the left side of the first end difference 51 is connected with the right side of spindle nose 1, left side, second-order ladder portion 52 is connected with the right side of the first end difference 51, right side is connected with the left side of axle body 2 by axle journal groove 53, and the external diameter of the first end difference 51 is less than the external diameter in second-order ladder portion 52. Owing to spindle nose 1 is connected with bearing, according to the actual service condition of mechanical manipulator, during installation, first end difference 51 matches with the bore on bearing, therefore axle journal 5 plays when axis servomotor is installed and stops and spacing effect, makes axis servomotor install structure firm, it may also be useful to stable performance.
The axle collar 6 comprises the first ring 61 and the 2nd ring 62, the left side of the first ring 61 is connected with the right side of axle body 2, the left side of the 2nd ring 62 is connected with the right side of the first ring 61, right side is connected with the left side of axle tail 3, the external diameter of the first ring 61 is greater than the external diameter of the 2nd ring 62, and the external diameter of the 2nd ring 62 is greater than the external diameter of axle tail 3. First ring 61 and the 2nd ring 62 are cylindrical or hexagon. Owing to axle tail 3 is also connected with bearing, during installation, 2nd ring 62 matches with the bore on bearing, therefore the axle collar 6 plays when axis servomotor is installed and stops and spacing effect, the cross section of the axle collar 6 is circular or hexagon can make it adapt to multiple installation environment, adaptation is conveniently installed, expands the scope of application of axis servomotor.
Axle body 2 side is provided with flat key keyway 7, for being connected with gear, transmits moment of torsion.
The end of axle tail 3 is provided with centre hole 8, for doing further installation.
Installation environment according to diffusion furnace mechanical manipulator, the external diameter that axis servomotor should be spindle nose 1, axle body 2 and axle tail 3 increases successively; The external diameter of the first end difference 51 is greater than the external diameter of spindle nose 1, and is less than the external diameter of axle body 2. This kind of knot mates the most with installation environment, it is possible to better connecting each parts, more effective transmission moment of torsion, strengthens its use properties.
Spindle nose 1, axle body 2, axle tail 3, axle journal 5 and the axle collar 6 outside are equipped with wear-resisting sprayed coating, and in working process, axis servomotor is not easy to wear, extend the work-ing life of axis servomotor further.
The process requirements when existence of centre hole 8 is to process axis servomotor on the one hand, it is possible to utilize centre hole 8 to do other and connect structure use, therefore, centre hole 8 inside is provided with internal spline 9, when utilizing centre hole 8 to install other parts, connect more closely and firmly, ensure the stability used.
The equal chamfering of left end in spindle nose 1, first end difference 51 and second-order ladder portion 52, the junction of the junction in the junction of spindle nose 1 and the first end difference 51, the first end difference 51 and second-order ladder portion 52, axle body 2 and the first ring 61, the first ring 61 and the junction of the 2nd ring 62 and the junction all fillet of the 2nd ring 62 and axle tail 3. Said structure coordinates with axle journal groove 53, it is possible to the internal stress that release step shaft produces after the heat treatment, avoids the crackle produced because of thermal treatment, it is also possible to avoid the crackle that in use stress is concentrated and produce. The right side of the first ring 61 is provided with compensating groove 10, and it is concentrated that it can avoid axis servomotor diameter change place to produce stress. Said structure can both strengthen the intensity of axis servomotor, avoids the infringement of extending stress band, extends the work-ing life of axis servomotor further.
Change the Flat dey joint of shaft head on axis servomotor into splined mode, make connection be subject to power comparatively even, due to because of groove more shallow, tooth root place stress is concentrated less, the strength reduction minimizing of axle and hub. Such connecting mode not only reduces employee with the labour intensity changing spare part, and extends axis servomotor work-ing life, also reduces the expense that spare part is bought in workshop simultaneously, and then reduces workshop cost.
